Mental State Examination

The MSE should be in the back of one’s mind when performing a Psychiatric History taking exercise.

The Mental State Examination Consists of:

    Are they clean shaven? Clean? Dressed? Smell?

  • Behaviour
  • What is the behaviour of the patient during the interview? Do they make eye-contact? Are the shifty? Do they look agitated or afraid? Is their behaviour appropriate for the interview?
